According to the City Manager of Graham: Please be advised that the Old Church located at 701 Grove Street in Graham Texas is currently located in a Commercially Zoned area, however as long as the purchaser of the property does not tear down the existing structure and build a new building they could remodel the structure for residential purposes. Our zoning ordinance requires a change to residential if a new structure is being built. Currently the Commercial Zone goes to the alley to the South of this church. So to summarize a purchaser of this property may remodel for residential purposes without changing the zoning.
This property is off market, which means it's not currently listed for sale or rent on Zillow. This may be different from what's available on other websites or public sources.
